T @ZZ whom llt may concern:

Be it known that I, THOMAS W. MARsDEN, a citizen of the United States of America, and a resident of Ilion, Herkimer county, New York, have invented certain new and useful Improvements in Gas-Holders, of which the following is a specification.

This invention relates to certain improvements in gas-holders; and the objects and nature of the invention will be obvious to those skilled in the art in the light of the following explanation of the example shown in the accompanying drawing.

My invention consists in certain novel features in construction and in combinations and in arrangements of parts, as more fully and particularly pointed out and specified hereinafter.

The accompanying drawing shows a construction within the spirit and scope of my invention in vertical section, the gas-supply pipe and water-pipe being shown broken away.

Referring to the accompanying drawing, 26 is a water tank or cylinder,`in the drawing shown with an open top and with a waterpipe 48, communicating with the lower portion thereof.

is an inverted tank, bell, or hood held in the water-tank by any suitable mechanism, such as the vertical take-0E pipe 36, extending throughout the length of the Watertank and secured to the bottom thereof and passing through the top of the inverted submerged tank 25 and secured rigidly thereon by suitable means, such as jam-nuts 27 28. The take-off pipe 86 has gas-inlet openings 43 immediately under the top of the inverted tank. The interior of the inverted tank communicates with the interior of the Water-tank, usually through the medium of space or passage 29 between the'lower edge of the inverted tank and the bottom of the watertank. The top of the inverted tank is shown conical in form, and I form a gas-chamber in the top of said inverted tank. For instance, I show disk 3l on the take-off" pipe with its edge engaging the top of the inverted tank at 32 and forming the bottom wall of a gascollect-ion chamber 42. Beneath the disk 3l I provide one or more disks (two are shown) 33 34, held in position on the pipe 36 by a collar 35 and properly spaced by Washers 37 38'. Transverse preferably registering openings 39 40 are formed through the several disks for the upward passage of gas into said cham# ber 42.

23 is the gas-supply pipe from a suitable generator and extending through the watertank and through the inverted tank and opening into the interior thereof above the Waterline and at a point outside of the gas-chamber 42 and preferably to one side of the several disks hereinbefore described.

For the purpose of purifying the gas I pro vide strainer-s 44 45 46. The upper ends of these woven-fabric strainers are attached to the outer edges of the beforeunentioned disks, so that said fabric sheets depend approximately as concentric cylinders within the water in the inverted tank. These fabric sheets are located between the gas-inlet into the inverted tank and the gas-outlet therefrom, so that the gas is forced to pass through one or more of said woven-fabric strainers, which are sufiicientl y fine in texture to catch, hold, and arrest undissolved matter or particles held in suspension in the gas, or other foreign matter, so that such foreign particles will be separated from the gas and the gas be thereby purified, as is well understood by those skilled in the art.

The water-tank is usually filled to a point above the top of the inverted tank, which is hence completely submerged and the interior of which is also lled with Water so far as permitted by the quantity or pressure of the gas in the top thereof. As the gas-pressure increases in the inverted tank the water-line is forced down therein, and as the gas is drawn off from said tank the water rises therein.

It is evident that various changes and modifications might be resorted to without departing from the spirit and scope of my invention. Hence I do not Wish to limit myself to the specific construction shown.

l. The combination in an acetylenegasholding device consisting of a Water-tank an inverted stationary tank within the watertank, a gas-inlet pipe opening into the inverted stationary tank, a gas-exit pipe connected to said inverted stationary tank, a disk supported in the inverted stationary tank and a strainer secured to said disk, the strainer and disk being interposed between the gas:- inlet pipe and the gas-exit pipe for purifying the gas, combined, substantially as set forth for the purposes stated.

2. In an acetylenegas generator, a gasholding device consisting of a water-tank, an inverted stationary tank within said Watertank, the inverted tank being surrounded by water, a gas-inlet into the inverted stationary tank, a gas-exit pipe connected with and leading out of the inverted stationary tank, a se' ries of disks and a series of strainers attached to said disks, the disks and straners interposed between the gas-supply pipe, combined substantially as set forth for the purposes stated. l Y

3. In a gas-holder, the combination of a water-tank a submerged tank therein having a gas-inlet and a gas-outlet, a support in said submerged tank, and a Woven-fabrick strainer interposed between the gas inlet and outlet and depending from said support into the Water in the tank, substantially as described.

4. In combination, in a gas-holder, a Watertank, a vertical gas-take-o pipe therein, an inverted tank in said tank and secured on said pipe, said pipe having a gas-outlet from the upper portion of the interior of said inverted 4 tank, a gas-inlet into the upper portion of the interior of said inverted tank,a support on said pipe within the upper portion of the interior of said inverted tank, and a depending fabric strainer hanging into the water from said support and located between said gas inlet and outlet, substantially as described.

Signed by me this 15th day of June, 1899.

THOMAS YV. MARSDEN.
